Can I use a NYLON Transducer in a WOOD Hull ???
Gary,
I stand corrected. FWIW, if it were MY decision I would go with the Bronze; because it's, well .. . . BRONZE !! {kind of matches my personality . . .} All joking aside, if ANYTHING penetrates the hull {wood OR 'plastic'} I want it to be the strongest possible material. Something that is 'plastic' or Nylon can be shattered or fractured if it is struck . . . have you seen what can float, just submerged, after a big storm ? In addition, anti-fouling paints easily 'attach' to Bronze fittings. I'm not sure about barnacles & Nylon, but I DO KNOW that 'slime' & algae WILL cover Nylon quite rapidly. However, if you already have the Nylon transducer and want to use it, here's how I would proceed. Make the penetrating hole about 1/4 inch LARGER than the diameter of the part that will go THROUGH. Coat the cut edge with epoxy, let it soak in a bit, then apply more, plus some fine weave Fiberglass cloth {an overlapping 'collar'} this will SEAL the wood from water penetration, plus stabilize the area. There should STILL be some 'slop' in the fit. After it 'cures' for about a week, clean the area with warm water and a bit of liquid soap, rinse well & dry. {this will remove any Amine 'blush'. 'Gun' a LOT of RTV around the 'mating face' of the transducer {typically they are inserted from the outside of the hull}. Carefully insert it - CENTERED - in the opening. You want a LOT of 'squeeze out' up through the opening. Carefully snug down the interior 'flange; NOT all the way - just get a good, even 'squeeze out'. Let the RTV 'cure' for about 24-hours. NOW tighten up the interior 'flange' and trim off the excess. You now have a 'Custom Fit Flexible Silicone Rubber Seal' . The wood is sealed from water inclusion by the epoxy/glass 'collar'. If there is any slight movement or pressure, it will be absorbed by the RTV Silicone 'gasket', rather than cause a 'point loading' on the transducer. Paint won't 'stick' to the Silicone, but it comes in Clear, White, and I think - Black. Let me know what you think, or if you want clarification. Regards & Good Luck, Ron Magen Backyard Boatshop {who has put Bronze chocks on his foredeck, and a 7 inch Bronze cleat for the mooring pendant} "Gary Warner" wrote in message ... Ron, Thanks for the answer but I *think* you and I are talking about two different things. Unless I'm not catching what you mean. This transducer is NOT a Shoot-Through-The-Hull type mounted inside the boat. (Also called an "In Hull Transducer" ?? ) It IS a THROUGH-HULL type where there is an actual hole cut in the wood. The transducer has a "mushroom" head on it and a "stem." The "stem" is pushed through the hole in the hull and the mushroom head sets outside the hull. SNIP |

Now we're on the same page.
I've go to reread your post again to see if I have any questions or concerns. Again, Thanks! Gary |
